Seems whenever we (friends) play on servers we either all crash locally or the server crashes. Wasteland seems to be among the worst. On topic though I never crashed on joining a server, but always after a couple of minutes.

Can you try it, when you join server with Escape from Stratis or Headhunters?

We need dxdiag and files from this folder for solve your problem. C:\Users\<Name>\AppData\Local\Arma 3 Alpha\

Can you upload somewhere in winrar package please?
When package will be smaller than 5,000k, so you can attach here. Thank you.
